Spicer was responding to a tweet from Rep. Maxine Waters (D-CA) on Saturday that suggested Pence was already "planning an inauguration" and that Spicer, along with former White House Chief of Staff Reince Priebus, was playing a lead role. Both have resigned from their White House positions in the past two weeks.

Mike Pence is somewhere planning an inauguration. Priebus and Spicer will lead the transition.

Walters has been a fierce opponent of President Trump and called for him to be impeached after he fired former FBI director James Comey, who was leading an ongoing investigation into possible collusion between the Trump campaign and Russia.

“Well absolutely, I think [Trump] can be looked at and perhaps even charged with obstruction of justice,” Waters told MSNBC's Chris Hayes on June 4. “You know, I’ve said all along that he would lead us to impeachment, and he’s doing just that. Every day, more and more is unfolding.”
